Hammond Power Solutions DM330CC - 3-Phase Transformer 330 kVA (230D-230Y/133V)

DM330CC

Hammond Power Solutions DM330CC is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 230V delta primary configuration and delivers 230Y/133V secondary voltage through wye-N connection, rated for 330 kVA capacity at 60Hz frequency. Constructed with aluminum windings and housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, the transformer measures 51.5 inches high by 39.5 inches wide by 34 inches deep and operates with 150°C temperature rise and 220°C insulation class. The transformer meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) with 60 dBA sound level and 4.5%-7% impedance, approved for installation in US and LATAM markets. Typical applications include industrial facilities, manufacturing plants, and commercial power systems requiring reliable three-phase power conversion. Key Features & Specifications
